1 claim. l

This invention relates' to improvements in fasteners, particularly fastening devices comprising rows of fastening elements and a sliding member to actuate said elements into engaged and disengaged positions.

An important object of this invention is to provide a sliding member which is designed to hold said elements securely and clear any obstruction in its operating movements.

A further object is to provide a sliding member, so constructed so that it will be retained in position with respect to the fastening elements, and will not slip and release said elements.

The nature and advantages of the invention are fully set forth herein and several embodiments are illustrated in the drawings. But this disclosure is explanatory only and changes may be made in the structures shown and described without deviation from the novel features defined in the appended claim.

On the drawings:

Figure 1 is a front elevation of a fastening device according to this invention.

Figure 2 is a section on line 2-2 of Figure l.

Figure 3 is a rear view thereof.

Figure 4 shows a blank from which the sliding member is fashioned.

Figure 5 is a longitudinal section of one form of sliding member.

Figure 6 is a similar section of another form of sliding member.

Figure 7 is a front view of a further modication of such a member.

Figures 8 and 9 are sections on lines 8-8 and 9 9 respectively, in Figure 7.

Figure 1G is a section of a still different form of sliding member.

Figure 11 is a front view of an additional modication; and

Figure 12 is a section on line Figure 11.

The numeral I indicates strips of cloth or the like having attached thereto along adjacent edges rows of fastening elements 2 of well known design. These elements are actuated in the usual way to engage each other and be released by a sliding member 3. This member has a shield 4 at the rear and a loose tab 5 in front to be grasped by the fingers when the member is to be moved. The shield is wide and extends above the member, and its front edge is turned over to the front, so that when the member 3 moves up and down, it will not catch and be stopped by a fold of the cloth or garment to which the strips l are conneetedn (Cl. ,Z4-205.14)

The tab 5 is divided at its upper end, by a recess 3 flanked by a pair of prongs 1. The front of the member 3 is cut to form an outward projecting loop 8, and the ends of the prongs 1 are bent-over and extend into the loop or bearing 6 from both sides. Hence the tab is pivotally attached to the member 3. In Figures l, 2,` 5 and`6 the tab is shown cut adjacent one side to form` aV tongue 9, bent inward to serve as a locking projection which clears the lower end of the member 3 to press against the cloth of the garment when the tab is swung downward, so as to hold the tab in place and prevent slipping along the fasteners 2. The strips 2 are attached to a divided garment such as is shown at l0 and Il.

When the fasteners 2 are to be engaged the tab 5 is pulled outward and the member 3 is drawn upward to bring the fasteners 2 together in the usual way. When the fasteners are to be released the tab 5 is manipulated to move the member 3 downward. To hold the fasteners engaged or released the tab is pushed down so that the tongue 9 presses against the cloth of the garment and the tongue binds against the lower end of the member 3 and is locked thereto. When the member 3 slides either way along the fasteners the shield or guard lfi prevents the member from catching any fold in the cloth and ripping or tearing of the fabric.

In Figures 2 and 4 the shield or guard i is made in one piece with the sliding mmeber 3, as indicated by the shape of the blank in Figure 4. But in Figures 5 and 6 the shield or guard I3 is a separate element secured to the member 3. The junction is effected by means of a projection I9 on one of these parts which fits tightly in an opening in the other. In Figure 5 the projection I9 is carried by the member 3 and the opening is made in the guard. Figure 6 illustrates the reverse arrangement with the projection i9 carried by the guard I8 and engaging an aperture in the member 3. In both forms the guard has a tongue 23 which is cut out and ts upon the top of the member 3; with its end turned down so that it grips the top of the member 3 snugly. In Figures 7, 8 and 9 the tab `5 has lateral projections or arms 20 which embrace inturned sides 2| of the member 3 to hold the tab in operative position when this tab is turned down about the inturned ends of the prongs 1 in the loop or bearing 8. 'I'he guard i8 has the tongue 23 as before holding the top of the member 3 and the side of the guard has projections 22 which grip the inturned sides 2l at the rear of the member 3. These projections 22 on the guard element are in line with the projections 20 on the tab 5; and when the tab 5 is swung to the position shown in Figure 8, the strips I bearing the fasteners 2 are gripped adjacent the ends of the fasteners between the projections 20 and 22 and the member 3 is held in place. The tab 5 is at the same time detachably held to the member 3 by its projections 20 engaging the sides 2l of the member 3. The projections 2D may have pointed outer ends, as Figure 8.shows.

In Figure 10` the tab 5 is shown with a projection I'I passing through an opening near the lower edge of the element 3 in front. It operates the same as the element 9.

The modification of Figures '11 and 12 shows a slide 3 with a guard 4 made identical therewith the same as in Figure 2, but instead of the loop 8, a clip I2 is riveted to the front of the element 3, this grip having its lower end bent over inward to pass through aligned openings I4 in the front of the element 3 and the tab 5. The upper end of this tab is fiat above the openings, and when it is turned down to cause the locking element 9 or I'I to engage the cloth, the clip I2 will hold the locking element in position. When the tab 5 is turned up the clip I2 is pulled out.

Having describedmy invention, what believe to be new is:

A slidable fastener member to unite and release rows of stationary fastener elements attached to the edges of sheet material, said member also having a pull tab movably connected to its front, an element at the back of said member having a tongue engaging one end of said member and bearing projections at the sides gripping the sides of said member, the pull tab having at its sides projections in line with the projections on said element to grip thernember and hold the pull tab to said member and to engage said material and prevent said member from slipping, said element having a Wide shield projecting beyond the end engaged by the tongue.
